SPEGIEIGATION forming part of Letters Patent No. 681,418, dated August 27, 1901.

Application filed January 7, 1901. Serial No. 42,399. (No model.)

To ctZZ whom it may concern.-

Be it known that 1, AL HAYWARD, of Warsaw, in the county of Kosciusko and State of Indiana, have invented certain new and useful Improvements in Heaters for Watering- Tanks; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in heaters for watering-tanks, and more particularly to the class known as submerged heaters, the object of the invention being to produce a heater which shall be simple in construction, easy ofoperation, and which shall be economical in the consumption of fuel, and one in which approximately all the heat absorbed by the body of the heater is utilized under the surface of the water for heating and maintaining the latter at the desired temperature; and it consists in certain novel features of construction and combina tions of parts,as will be hereinafter more fully described, and pointed out in the claims.

In the accompanying drawings, Figure 1 represents a view of my improvement, and Fig. 2 is a View in longitudinal section of the same applied to a tank.

A represents the body of my improved heater, preferably rectangular in plan and having straight side and end sections, the rear portion of said body being curved downwardly from front to rear, forming a depressed section, as shown in the drawings, so that when the heater is placed within a tank of water,

as represented in Fig. 2, the reduced portion thereof, as well as the major part of the body of said heater, will be submerged, thus providing an extended heating-surface and one in which approximately all the heat generated is utilized in heating the water, whereby the water within said tank may be more quickly and economically heated than heretofore. This depressed portion is provided with a pipe 1, preferably formed integral therewith, the top end thereof being approximately in the same horizontal plane with the open elevated end or fuel-opening of body A and is adapted to receive and support the smoke-flue 2. The fuel-opening of body A,

just referred to, is located in the elevated portion of said body, as will be seen by reference to the drawings, and through this opening fuel is passed to the fire-box, the passage of air through said opening being controlled by the slide-damper 3, which latter rests and slides upon the inclined flanges 4, carried by the respective sides of body A. In order to increase or decrease the amount of air passing through this open end of body A, I have provided the rear face of damper 3 with a series of teeth or notches 5, adapted to engage the upper edge of the rear wall of said open end, whereby the damper 3 may be supported in any desired elevation. When the damper is in its lowermost position, the space between its lower end and the inner face of the front wall of body A will be practically closed and draft to the fire cut off, and when in a position so that one of the uppermost notches or teeth engage the upper edge of the rear wall of said body an opening between its lower end and the inner face of the front wall will be formed, thus permitting of the free entrance of air to the burning fuel, whereby a draft will be created for the fire. This space may be enlarged to increase the draft by simply moving the damper in an upward direction and booking it, as above explained. The damper 3 is provided at its upper front end with a hook 7, through the medium of which said damper may be supported in the position shown in dotted lines, Fig. 2, when it is desired to add a new supply of fuel to the heater.

The bottom of body A is slightly inclined from rear to a point approximating its center, from which point it is depressed rather abruptly, as shown at 9, Fig. 2,which depression constitutes the ash-pit,across which latter extends the grate 10.' This grate 10 is preferablya cast-metal plate provided near its outer end with perforations 11, so that the latter come directly over the deepest part of the ash-pit.

The frontsection of body A is provided near its lower end with a drain-pipe 12, the inner end of which communicates with the ash-pit 9, whileits outer end is designed to project through the tank, as shown in Fig. 2. When it is desired to remove ashes from the fire-box, they are first drawn upon grate 10 and to rod a position directly over the perforations l1, and their passage through the latter is eifected by pouring water through the fuel-opening onto said ashes, and after their passage into the ash-pit are drained of]? through drainpipe 12.

From the foregoing it will be seen that a self-draining heater is obtained and one in which all moisture accumulating therein will readily and quickly pass ofi to the ash-pit, and from thence to the outside without coming in contact with or polluting the water in the tank.

In order to prevent moisture that accumulates on the smoke-flue above the water-line from passing into and polluting the water in the tank, I have fluted or corrugated the lower end of said smoke-flue and have pro vided the upper end of cast pipe 1 with a collar 13, into whichlatter the fluted or corrugated end of pipe 2 is seated, the collar acting as a cup, and hence it will be seen that all moisture collecting on the outside of due 2 will pass within collar 13 and not into the water.

As previously stated, Iprefer to construct body A of cast metal, and in so doing 1 corrugate or rib the exterior surface thereof, thereby imparting additional strength and a greater heating area.

It is evident that changes in the construction and relative arrangement of the several parts might be made without avoiding my invention, and hence I would have it understood that I do not restrict myself to the particular construction and arrrangement of parts shown and described; but

Having fully described my invention, what I desire to secure by Letters Patent is 1. A tank-heater, comprising a casing having an upward open extension at one end and means for attaching a stack at the open end, and a damper projecting diagonally into said upward open extension and means at the upper end of said damper for adjusting the same.

2. A tank-heater,- comprising a casing having an upward extension at one end and means at the other end for attaching a stack, a slide or damper disposed diagonally in the upward extension of the casing and having a series of teeth to engage the upper end of the wall of said upward extension to retain the slide or damper at difierent adjustments.

3. A tank-heater comprising a hollow elongated casting having corrugated walls, and a fire-chamber, and having a smoke-pipe at one end of said casting, the other end of the casting having an elongated upward extension provided with a damper, and an outlet for ashes communicating with the enlarged end of the casting at the bottom thereof.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses AL HAYWARD. Witnesses:
